New ones (Miz blue attire and Mcintyre WM 26)

I'll talk Miz first, it's very good. It's a simple recolor, but very clean. It could be cleaner, especially around the very top part of the trunks. I like how you got the little part showing on the boots, it's a small detail that some would have left out.

Mcintire isn't as good. I hate when people use the "negative" thing for black to maje it white, or vice versa. I'm not sure what program you use, so I don't know what tools you have, but making black into white can be difficult. I desaturate it as far as possible, then play around with the brightness to make it more white then grey, but not too bright that it fades into the background.

Not a bad start to PS figs bro. Maybe next time try out head swaps/part swaps, and eventually work up to making heads yourself.
