You have a very good start there.
One point I might make...Sometimes too much detail is a bad thing. If you just go for a "suggestion" of shape using veining and keep more of the wood and less holes, it can improve the overall look of things. But, that is just a personal point of view.
I am a "KISS" kind of guy (keep it simple stupid) I feel that about 25% of hole and 75% of wood makes things look a lot more interesting. Especially if you have interesting grain in the wood but, even on a plainer wood such as Baltic birch plywood just a suggestion of shape like in a sketch attracts attention.
Just my two cents worth.
