Your lines are getting there. Keep on exploring. When you start shading, i would really stick to planes. Learn them asap, so you can more easily know where to start and where to go. Think more of planes, instead of spots.
need to practice environments as well, after watch Whit's ( aka Mr.Blonde ) video ( which is freaking awesome xD ), made me realize how much stuck i was on characters ^^; well need to pratice all ( enviro, characters, creatures ... Worlds! )
cool update, like the wicked mouth in post 316. And the nice compositionm you managed to create with the plants in the same post... You should keep at doing environements directly in color , the ones you did are great. Its always better to start with a background color close to the ambient color of your environement and work from that with silhouettes and mass of colorl.. then you pick up a lightsource/direction for your sun or whatever light it is , and start having fun from there =) The environement in 304 with the rock is great... it got a nice ambient light going on, i like the little blue you added on the rocks, it feels like a clouddy day because the sun light is kinda dimmed, you should try to do another version with a strong sunlight. And im still jealous of your lines.. ;P
cool stuff dude! watch your heads though, some look a little misplaced, keep in mind the construction (skull, muscles) when sketching them. really like the octo page a couple of posts back and the plant sketches look great.
nice speedy callops, you should give it a few more hours, it would greatly bvenefit from a few strong specular highlight to get that slimy feeling, it would also be a good opportunity to study how reflection works to create speculars on slimy surfaces strong speculars where the light reflects to us, and usually bright contours because the surface is reflective. I really like the composition of the picture, dont know why but wide canvas always look better than square ones hhehe. Thanks for commenting my SB btw, its really motivating !! Keep it up , where r u from by the way ?
