it's definitely a sig
400x300 is somewhat standard. obv not as popular as 400x200. I think it's 400x300 at least, or around it.

1. Render placement is weird. It feels a little small. A tip from gorlab was to place it so the top of the helmet is off the screen, kind of like whats going on in your lefthand sig
2. Render looks out of place, it's too bland for what's going with the rest of the background. I'd play with levels/curves and get some more changes to it.
3. Your text looks like one layer where you typed "Jared Spaz" and just pressed enter after Jared. Make multiple text layers so you can move the words closer together.
4. The effect on the text doesn't really fit in with the rest of the sig, although it is kinda cool
5. Maybe move the render close to the middle, it's usually a good idea to have the eye drawn to the render and since it's off to the left the main thing im looking at is the big Spaz in the middle
6. The background and the diagonal stock thing is cool, i like it.
7. Dunno whats going on with the glove and pants, it's like there's something overlaying it thats making it look off colour.
8. Try adding some lighting to your sigs. An easy way to make it look like there's lighting is to take a soft brush, size 200ish, and put the flow onto 20%. Then click above the head once or a couple of times. If you don't know what I mean just dm me or something.
also i think your sig for berocka was the best thing youve made
Do you use photoshop? I'd suggest downloading Topaz labs. If not I'll hook you up with photoshop if you want.
