Concept Art- Great Beasts

Awh dang guys!
Its been way too long since I did some concept art! I miss it!
Always loved it, dam I got my starting on concept!
Anyway this is essentially a group of art class doodles ive been doing instead of actually doing any work ...

Anyway the four winged creature, well it wasn't really based on a piece I saw on here, but I was thinking about it when this was I drew that one. SO it bare a resemblance to it. Those who would question me for art stealing because it might look very similar, I did i not trace, no reference. This was all in my imagination so shove it.

The bird creature... was originally supposed to be a raptor of some kind, but whateves.

The random giant head stick out from the bird is actually a head of a tortoise like monster, just got to lazy to do the rest of it... uhm
OH yea and the goblin kind of creature, I honestly dont know what that is but meh... they're just doodles so yupp.

Agh I miss concept art!
