good job on the colors... so the girl who is sitting is winter...? it would little bit clearer to see that the plant is spring if you can add small touches such as a small face on one of the branches and perhaps shaping the branches to resemble arms... good luck...
NIRONERU : I had at first added a figure but then actually decided against it composition wise. I decided to let the hummingbird represent my version of spring, and keep the plants looking natural. But thankyou those are some good suggestions!
ktkps : Thankyou!
Next time Im going to try paste a WIP up. Otherwise heres a small closeup.
