thing is, they're not 'blobs'. They're simplified shapes of what's to come, but blobs is thinking about it entirely in the wrong way. I've just simplified shapes and then worked my way in to a more detailed drawing, you can keep going and going until you've detailed the hell out of it, but the same principal applies... Trying to get too detailed too fast will usually end up with a nice detailed mess without the right structure unless you've already gotten that stuff down.
Fighting the delusion that the computer makes you better, one noob at a time.
