I think the website is too dark. Or, if you want to remain that dark, I suggest you change the gradient, its too much contrast and does not look modern. Try a bright at top to dark at bottom gradient, but starting at #222 ending at #000.
Also, the color combination black - red (hover) is very negative and also too much contrast. There is no color scheme at all on this page, since you are using black, red and all other colors in the logo. Maybe you can try the dark colors (222, 000) and some popping color like bright turqoise and a darker turqoise to match.
The font size is too small for this little content, and the button text is not centered, try adding line-height: xx; which is the same as the height of the button, then it's centered.
I hope I could help.
