Hi Caleb,
First advice I can give is that it might be beneficial to upload your portfolio in a different manner. I had the link open on my browser for over a half an hour and only the first page loaded.
Edit For some reason today its working much faster!! I agree with what Ralph has said, and I will also add, I think you could make your sketches stand out a bit more, scan them in differently or do some digital sketches over top. They just seem very washed out and in many cases small. Keep pushing, you’re onto a good start!
