yes, i am totally new to photoshop and graphics, feel free to class me as an amateur: All renders where taken from these forums, thanks.
A lot of weird sizes and you seem to use a lot of brushes check out some tutorials one trying things other then brushing over your render I do enjoy number 2 though
a few things: I feel like a lot of these signatures are lacking flow. and most of these sigs are very under-contrasted and grey. I like the first one the most but after that it is a bit boring. try some tutorials to liven up your sig making
