Well done! Love your beard and your hat
Suggestions: As Scott wrote, be aware of "stuff" coming up/out of the head, yourself or others you may portrait.
The picture are a little to bright for my taste, which wash away some of the colors.
I like this one, but since you have a hat, you could also try some images not so much directly fronting the camera, move your body a little to one side - you could also move a little more away from the wall and work more with the shadow behind you.
Last, maybe pull your glasses a bit up? We wanna see the enire eye of yours
