*Did the first one in the art board*
So anyways, the second one is probably my least favourite out of the three. Mainly due to the floating head syndrome!
Never, ever just use the head as a focal point, always show some neck or the rest of the body. Can't really remember why but it does look kind of strange.
The depth in that tag was also quite off. The focal looked really flat. I tend to try and keep all effects off the face of my focal.
The tag is also kind of bland, could have really used a few more effects and colours.
Loooove the third one. Really nice effect with the guitar.
However, you're kind of having the undefined focal problem again, mainly on the left side of his face. You're kind of over-blending if you get what I mean.
The lighting is also kind of off. The lightest part of the sig is on his right hand side but the lightest part of his face is on his left. Remember to make sure your lighting is as natural as possible.
This sig is also kind of bland but it does have a really nice feel to it. I hope you try experimenting with a few more effects eg, fractals, c4ds and keep playing with clipping masks. That effect on the last one is so hawt.
