Help with my jetbike

[jmyser]

Hi all, fairly new here, but I thought I'd ask for some advice on a piece. Most of my stuff gets to a point like this, and I just get a "meh" feeling about them, and just never finish.

I was hoping some fresh eyes could spot where this needs some work, because I'd really like to get past this wall...

Thanks...

edit: Sorry, now that I look at it again, it's still pretty WIP, so I understand if it needs moved, I don't see a way for me to do that.

compositionally, I think something like this would be more interesting. Try to lead the eye into some never-ending triangles. This is a quick and sloppy paintover, but I hope it helps spark some new ideas.

I would try to figure out when this is, who this guy is, and who is chasing him. Design the jet bikes accordingly, and what he is wearing. ( I gave him a backpack for like a parachute or something. Figure out where is flying over, and why. A redesign of the jet would be nice. More aerodynamic, and a intake thingy...or something...*Shrugs* I dunno. I think the reason you lose interest in your sketches is because they aren't really telling a story.

Also, pump up your saturation for the guy, and desaturate the surroundings a bit to draw attention. Contrast of saturation and hue value. (something I didn't really do is:) pick a lightsource and work with that direction for the lighting. When working digitally, or painting, it is a good idea to get the shape of the form, and then put you fine details in.

Wow, thanks. That's a lot to consider. I'll have to see what I can do with this thing.
