decent
You should practice your perspectives. That Left knee that is up needs to be bigger. When something is closer to the viewer, you have to make it bigger to create the illusion of depth. The fireball doesn't fit in the picture because it is don't like a painting and smudged while the rest of the whole image seems to be vector. Not a good logo. Logos are usually not very complicated and are simplified so you can replicate them easily. A good logo is something you can draw in the sand with a stick. This is too complicated to be a logo. It is decent, hopefully you'll take some of this advice and use ti to get better. That right hand is also a little big compared to the front one (which should be bigger since it is in the foreground).
