Realy nice site! I like your Modern web design and the hover/animation effects.
I think, that would be better for the visitor to show him, more details from your portfolio page. If he likes a website from the thumbnails view,
not to just land him to contact page. But to has the abillity to see more pages from this site. If you dont want to show him the link,
you can show him more photo/pages from this specific site. Like photogallery style.
Keep the good work!
