youre a few more steps away from making some solid stuff. this a bit washed out and could use some better coloring. idrk what you do throughout a sig but this is missing a few things. youll get it over time.
i did this(nothing special at all) but i added the psd so you could see some minor things i did on top of what you have --
too much saturation contrast on his face... desaturate some layers and lower the opacity. i like what pugzy did with it. download the psd and learn from it haha
