Monster girls 1,2,3

First three of the monster girls. Harpy, Centaur and Slime.

The first two are a bit meh but I like how the Slime one came out. The Harpy shows how much I fail birds, Centaurs are the most awkward mythological creature ever imagined and the Slime was too much fun. >.<

For those that don't know I'm doing the 30 monster girl challenge (its on my page) They will be mostly quick crappy doodles to practice anatomy and so on so don't expect works of art here. These are purely practice but I am open to advice on all of them.
If I like how any of them turn out I will post them seperately otherwise they will be in sets like this.
So yes... Have fun. I should point out I didn't look up references for these I just went on my own inturpertion (thats not how you spell it but its late) so don't go pointing out that 'Harpies have hands what you doing?!' or something like that. They aren't real anyway fhsldgkhsl
