lol every where dude u need to do some more detail before anyone can tell whats up i meant looks like a cracked tree, so far good but add more ya know leaves or bark if that
trees don't bend with their breaks. make the edges super jagged and rough when you want to make anything broken. maple and lolz do this really well, so possibly look at a couple of those two's tracks for some guidance on the matter.
There's only gray and black so you gotta imply that it's ice through everything else around it. It's kinda like the case with fire, you gotta imply that it's fire. With fire there's smoke, and when you draw smoke you have a good opportunity to distinguish fire from smoke(fire is bright so let it be mostly white contrasted against grey smoke). Example: I'm kinda being lazy so it's quickly brushed, but if you took your time the results would be much better. I've never bothered with snowy-icy-artic-winter type tracks therefore I've never really tried to draw ice before. But after taking a quick look through google images here's my attempt at icicles: Now from here on further imply it's ice through its surrounding environment(such as with snow). Keep in mind ice is translucent so draw as if the light isn't passing right through, which is what I tried to do with the grey. Finally, if you are drawing really cartoony then I don't even know why I bothered answering with all this.
