Ding repair progress

Alright guys, just got a pretty good sized pressure ding on my two week old board the other day. Decided to try and fix it myself. Sanded it down, put two layer of glass and resin. At this point I’m feeling like more of a mess of it than if I left it. After drying there is still the pretty good sized indention. This is pre-sanded to put the hot-coat on. What should I do? 

Sand it and feather the edges of the glass before another coat of resin.  Repeat until satisfied.  Then wax it up and go surfing!

What kind of board and which construction is this?
