Not to necro or anything(I'm totally necroing), but this is still a good idea... I'm not gonna build it for you, of course, but I can give you some advice if you want. Being artistic a good builder need not be. I've got a terrible art sense myself, but the constraints of voxels makes things very easy to look good. Alot(and I mean ALOT) of voxel building is trial and error. Eventually, you build up a sense... after, like, a year.
Personally, I've been block building since 09' and I'd say I'm somewhere in the top 10% of voxel builders(Essentially, I'm counting anyone that has built something with the intent to impress). That sounds pretty lofty, but it's not. The builders that would normally construct statues like the one I plan to build without creating a blueprint beforehand are in the top ~.02%. There are no more than a few dozen epic builders, but getting to 10% is easy. There are millions in that 10%, but it takes effort to get there. I know you're not predisposed to enjoying building though, so it's more challenging to git gud, without doubt. Who knows, though? Once you get the hang of it, you may come to enjoy the process.
It's spelled "obstacle", btw... for future reference.
EDIT: I tried drawing some stuff. I'm not as bad as I thought, lol.
