Congrats on your one year thread and the celebrating picture looks great with lots of nice colors.
I like this one as well, the first one looks cute because his eyes look very innocent. I think it looks very much like a banana on their head, that makes it really unique. I've seen a lot of fakemon around lately (Mainly sprites) so this is kinda refreshing.
This makes me think of the water type more than posion but the purple tint gives some sort of poison to it.
For CC, I am not an expert when it comes to CC as good as the fakemon are in this picture it looks overall pretty empty and makes it look like they were lose. Maybe it's just me but I think a background would be great to give it an atmosphere. Even a background color like the one in your one year pic could bring it to life more.
Nevertheless, I like the coloring on this one.
Some little suggestion, have you considered experimenting with different materials? Tissue paper? Beads? leaves? Old materials ect or maybe even paint or felt tips. Certain materials and medias can give an extra or much fuller or vibrant effect, whilst the pencil drawings give a gentle effect.
Now back on your first page of the thread where I see much more of that work. Sorta brings back memories because I remember the Miltank/Taurus Pre-evolution, I can't remember if I commented on this thread the first time or not so apologies for the bad memory.
Now I've seen you've used a range of traditional media including Gimp. Something tells me that the posion one would look really nice with some GIMP effects.
Overall, I must say you have quite a natural style.
