yours looks pretty good
but im wondering, did you laminate the wood?
its when you take thin strips of wood and glue them
together
this is done to make the board able to flex without easily breaking
most skateboards are made by laminating the wood but yours looks like you just shaped a piece of 1/4" or 3/8" thick wood or something and stuck trucks on it
however i do like the shape
and i like the idea of ocean designs on the bottom
heres a couple snapshots of the longboard i made
its not actually homemade, i build it in woodshop
although i did design it and build it by myself so w/e
its 5 feet long made from 5/8" poplar
i didnt paint anything on the underside, just used some woodstain to make the grain of the wood show better and look nicer
ive got a second one ive made since that one thats about 3 1/2 feet long
i didnt post pictures of that one because i havent gotten around to gripping it or getting trucks and wheels on it
that one i woodburned a design on the bottom
the design is the letters of my name rearranged to look like a guy skating
i think the shorter board actually looks better but its incomplete
