Like the topic says, I'm extremely new. If something is wrong(as I'm pretty sure there is and always will be), please point it out and tell me how I would go about fixing it.
I spend a lot of time just drawing and scrapping set ideas(especially arms) and my biggest goal at the moment is to make a set based on the Black Knight from Dark Souls

Hi there, new guy and welcome!
You got the tag right, so cudos for that but you'll also have to add the software used to make it! ;)

Feel free to edit this away.

Thanks
I used Photoshop CS6

That's way better than me bro I'm like XD

You should practice mapping, shading, details, etc. Find your own style, don't try and steal other people's style even if they look good, it might not be the best way for you. The head you made is mapped okay, but it's pretty simple and plain so far. Before you attempt to turn the black knight into a set, practice a bunch more, and get a lot better at texturing. Good luck! :>
