Slimlines are far from boring and are sometimes the hardest to get correct.... Why do we all start with them... Oh because they are cheap.... When done correctly and I don't mean like a woman with a belt on
you can have some of the thinnest sections of timber to work with, between 1.5mm and 2.5mm generally, grain orientation is also important, which we don't need to do on single tube kits, that we 'progress' onto.
I love a good quality slimline presented well [MENTION=603]Bill Mooney[/MENTION] has terrific shape to his pens(Patents pending) as does [MENTION=122]Penpal[/MENTION] so maybe check them out, but stick at it..... That looked to be a very nice piece of wood too,too good to nail to the wall!!, personally, I'd knock it apart use a 'streamline' ring for girth or normal kit band and maybe refinish it with melamine laquer as experience.......
Don't knock yourself too much,
BTW don't take photo advice from [MENTION=2366]Garno[/MENTION]
