IMO, any build is a significant undertaking. My advice is to take your time and plan it out the way you really want it the first time. If you don't, once you start building and realize what you've gotten yourself into, you will want to add those features anyway (and it will be harder to do at that point).
Although it seems that way sometimes, these things don't just pop out 2 or 3 in a row; and they almost always end up costing more than estimated (... especially if you keep track of receipts!). A build takes time no matter how simple you plan for it to be, more time than you would imagine at first (... but I can't claim to be an expert on that subject, so consider the source on that one

). So my advice is don't worry about adding a few features or some character into the plan. Do it now at the planning stage and it will be easier.
That sketch of GPW's is not complex, much at all, once you have the tools out and get working. (In fact it is the current inspiration for my #2, if there is one.) Even a simple slanted front corner is better than a rectangular box.
Just trying to be encouraging. If something is worth doing, it is worth doing well the first time.
