I like the Halo one the best, Invader Zim seems a little unfinished to me but idk what to do with it... Also these are my first sigs in like...5 months...plesh be easy :] C+C please...
Text is a 'make' or 'break' effect. Here, it breaks...badly. First thing I saw on your halo signature is the text, which isnt whats supposed to happen. You eyes are suppoed to look at the render and the surrounding effects. Having a background which is constant ruins it, it needs to have some effects in it and look more to suit a Halo render. Maybe even some colour balance, curves and gradient maps could fix it!
Would have to agree with Adzi on the Halo sig, the text is way too large and stands out more than the render with the color contrast. Tone the text down a bit and add some sort of effect to it. Good start after a 5 month time period though.
