I might try to use a different too. I thought he was cutting his arm off not carving a broken heart. I really like the design and I agree with cartooner that you should work with the placement. I also like it on the fourth color, sand I think?
Took White out of the color palette, picked a lighter shade of Gray, and added Red again. I repositioned the placing on the shirt and made a few other minor revisions.
Colors:
Black, Light Green, Green, Light Brown, Brown, Dark Brown Crimson (Deep Red) and Light Gray.
I like what you have done with it. The knife is a better tool to use. I really think it works the best on sand. For the placement maybe try starting it down in the bottom left corner and then you can rotate it so it is going up the shirt. I really like it!
Did some relatively minor changes. Added some blood around the heart and on the knife, as well as a few drops, but they are tiny and only noticeable on close inspection.
I re-adjusted the placement, similar to how MeinenM suggested.
Was thinking about it on white, but I settled on army green, its a nice and neutral shade, doesn't drown out the light tones or the dark, and army green can be worn with pretty much anything... :D But then again so can white.. I'm resting my brain right now, don't wanna think about much for an hour. Hah!
Thanks for the comments everyone, very much appreciated!
I made it so that it looks like its being held between thumb and forefinger, I didn't make the "hands" too hand like because I didn't want to personify the tree too much. :)
normally we would :D but Treemo's got leaves covering the knife handle, kinda like the tassle on a spear, meant to confuse the eye... hahaha just kidding.
But yeah, the knife handle isn't visible because of the "foliage".
This is my 2nd submission, feedback? :D
8 Colors used: Light Green, Green, Light Brown, Brown, Grey, Black, White, Red.
