Interesting style. It has good effects but maybe try using them sparingly instead of over the whole sig? Use the effects in this sig and try mixing them with other ones (like smuding, softer brushing, etc)
It's good for a nooby sig. I think a black border would have been nicer to match him but meh. It's way oversharpened in some areas and the effects aren't bad. Although like kiyaa said don't use em all over the sig. Put them around the focal and make more effects around it. It's good for a nooby sig, good job mate
Your focal blends there too much, also there really isn't a lightsource, the brightness is the same everywhere on it. a tip: Don't leave any effects over your focal/focals head, around it yeah but not over it
