Not to bad buddy The only big problem you got right now, is making the render flow better with your background, you have to much effect around the render, so it stands out way to much. Try and make him fit in more, and not pop out so much I do like the background you made though very nice Get rid of your text and I'd like the tag even more <3 Also you don't really need that boarder you have, most tags *to me* look better without them. One big tip I can give you though.... Is when your creating a background for a signature, don't make everything so transparent and bright behind all of that, try and get some solid figurers to make depth and structure within your tag.
I'm tellin you get rid of the boarders!!!! Great job on the left side of the signature, it has a much better background now, it's more filling same with the right side. Now to address the main problem. Think of your lighting in any art work you do as realistic. If that much like was coming from behind the halo guy do you think you would beable to see him like that?? NO!!!! He would be very dark and you would almost be unable to see him atleast the middle part. Now that doesn't mean go insane and make him dark as hell, just slowly make him darker until it seems proportionate to a realistic point of view, and post a V3 I would also like to add that Version 2 is much better
Okay I'm gunna have to say V2 still BUT!!!! listen first Version 3 is really great because - You used the lighting that was already on the render and make your light source come from the right. - It's also better because you got rid of the borders. Reasons I don't like it Well you took what I said out of proportion, I didn't mean darken your signature I like the lighting you had in the 2nd version, I was just saying don't have the middle of the guy so bright dim that part up and keep the lighting behind him. You do have a much better idea of a solid background in this, but I think Version 2 was much better the background was solid, you had effects and your own lighting, all you needed to do was change the way the render was lit up. I'm not hating and sorry if I'm making it difficult but nice job, I think you should toss up a Version 4 <3 kuz I like the improvements your already making to your art.
I prefer how the render is done in V3 than V2 but I like the lighting and effects of V2 better. Just combine the two (not in a literal sense lol) and you're set .
