Hope I’m not to late to the party. I have a suggestion that kinda gets to me.
On your projects page I wouldn’t necessarily try to use the entire image for that small thumbnail. Maybe do a cropping of a section of the website or piece that stand out. For instance maybe the logo or something in the design that is striking.
Also look into setting up a contact page with areas for people to fill out. This appears to be more professional.
I am glad to see you broke out of the normal flow of structure websites tend to be leaning toward these days.
