Made these in yearbook class today... i was very bored and did nothing at all lol... other than this... anyways, i had no special presets, no downloaded brushes, and finally they were on a mac.. so no right clicking.. (gah!) and a harder interface for me to understand... (i use PC obviously) so heres some stuff.. just for fun, and very basic This one i made with another girl who i was teaching to use photoshop. she made a separate one on her computer. we each made one totally from scratch, which was pretty cool the only other kid in my class who can photoshop showed me a fun brush setting...
I love the first one, looks like it was completely scratch so I'm impressed. I can tell what you did for all of it, but it's still extremely well thought out. Quite nice. The caterpillars don't really look like caterpillars... Uh, I think the only thing I could suggest for those is to add a clipping mask of a color to overlay on top of them. For instance yellow or such.
