Thanks for your suggestions. These are all very good points. Regarding "appwork", it's my company name. Originally I wanted to call the product Appwork Sketcher but probably no one will know what it is. So now I call it App Sketcher. I will remove appwork except for the company name in the footer.
- Might want to have hover states on the other navigation buttons.
- Too much text above the fold, in my opinion. If possible, I would highlight some short, bullet-points near the top (in larger font)
- What is "appwork" in the top left logo and in the title? Everywhere else seems to call it "App Sketcher". I would try to be consistent or make the difference clear.
