I stuck with the Nico Robin style and tryed a coupld of new things. I personally like it... V1 V2 V3 V4 Comments? Ratings? Which is better?
I love the background. as for the render, i don't really like it, its a bit dark for the signature. I like the text but the M should be a bit darker. Overall its really nice, I prefer V1, its lighter, but only a tiny bit.
... Is it wrong that I don't see a difference? xD Well anyway, I like this style a lot (as you know), but work on the colors more. The render isn't matching the background very well. Before you do your coloring steps, do a black and white gradient map and set it to a low opacity. It will dull down the colors a little so that they work better later on. If you don't use gradient maps of anything, duplicate render and cover the sig with it. Blur it at a very high setting and change the layer mode. Text isn't bad, but add some negative space. Some pentooling might look good here as well.
Last cnc im doin today ;d It's not really too different. It's a follow-up tbh. Try to make it less contrasted. It's really contrasted on the right. The text can be better. The render doesn't really fit with the colors you used for the background. To make it flow I thought you'd use the orange-ish gradient you do on most of your tags. I'd go with v1, 3 and 4. Two is my disliking. Otherwise, you are officially in a slump. GO GET BETTAR =D
I don't see a differnce between the versions. But there okay signature, maybe adding some text would not hurt but overall I like them.
