of course bootstrap et al are the first place to go, but i was referring to one step further in design. Like custom look and feel, some marketing material, nice typography, infographics, nice app UI/UX design (visuals, effects etc)...

I know good stuff when i see them, but don't know how i can create them. The real problem is i cannot figure out my way to gradually improve my skillset and get there. :( That is actually my problem and the reason why i asked the question in the first place.

But thanks for the answer anyway... Cheers!
