Painted this recently but I feel like it could probably be pushed a bit more, so crits are welcome.
3 things jump out at me immediately:
1) Youv'e started to hint at the sub-surface scattering on the wing membrane, but you need to push it alot further.
2) The pose of the legs just isn't right for a creature in flight. You need to reference bats, birds, and flying squirrels.
3) The wing membranes are going down his body and disappearing into his...blue jeans. You need to re-think how the anatomy of the wings works with the clothing choice.
As the ego shrinks, so the spirit expands.
I see what you did there. I think.Leather Wings
The forearms are too flat and straight-sided. And where's his fifth fingers? Exactly what part of his jeans do his wing membranes attach to? Why are his jeans frayed into frills of neat strings at the bottom, but otherwise in good condition? Why the big orc-tusks?
Well, the most obvious thing I might suggest would be to show the light of the moon through the wings:
Realistically moon wouldn't be likely to give strong enough light to do that, but... and you could use that to confirm the shape of the moon and where it ends (and if the moon is strong to give highlight to his body, then it really should light his hair too). Or you could work out the composition more, have more of the moon visible and the man bat be framed by the moon... Overall I would take this back to the thumb level and explore more of the compositions. Right now everything's just in the middle and that's it.
To me, nothing much is conveyed in this image, through the composition or colours. It's not very dramatic or exciting, but it's not sad or calm or somber either. The character just kinda is, and though this would look more like a calm "just flying and chilling, taking in the scenery" type of pic, the background or colours just don't really give anything either. The colours are fairly gray-ish and don't really convey much mood and there's couple clouds but there's no good feeling of height or distance, like if we could see the top of the clouds disappearing to the distance or see some small lights down below...
This post had similar kind of moon and night scene and you might find these paintovers helpful: http://conceptart.org/forums/showpos...9&postcount=34
Also, where does his wing membrane attach? Like his pelvis is seen from the side (or more like his feet are seen more from the side which makes it feel like his pelvis is twisted more too) but the wing membrane just disappears somewhere beyond his pants... So does it attach to his pants? I know this is something that people usually just handwave because they probably don't want to come up with a solution that would work but it's a pet peeve of mine.
Also his other leg looks pretty long compared to the other. With his knee raised so high, I'd see his other heel is on the level of the other leg's knee, but whether it was attempt at foreshortening or something, it looks wrong to me.
Well... I thought it would look bad if the wing membrane had a small attachment, because I don't think that's very practical for flying, and I couldn't figure out how to make that work with the clothes. But I guess it looks a bit silly...
But thanks for the crits. Tried to improve it a bit
And this was really just a doodle that I started rendering. I probably should've planned it better... But I think I'd rather take it as far as possible now and start something else more serious than start over with this.
Besides the membrane body attachment issue... I think the legs need a lot of work. The first thing I thought is how uncomfortable it would be to bend my legs like that if I was flying. If he was going real fast, they'd flatten out like the image below. But human legs are more heavy than bat legs, so I assume they'd be hanging down. Unless his wings attached to his legs, he'd be flying almost vertically while frantically flapping his wings and bobbing up and down, because of the weight distribution, which is why this pose looks so off to me.
