Nicest job on being totally, so well-rounded on your 30 minute class mode there. Nice broad strokes and solid forms, great going! Marvelous job, kumotori!!
Well, if I was to help you out, then what's your goal? And another thing, my advice is to help you out on making your organic shapes and forms more fluider and loosest, by means of going through 156 minutes of 26 second stroke sketches?? (156 x 60/26/2 days in a week, 9360/26/2, 360/2=180 sketches a day) The reason why you'd do this advice is because of two things: First of all, it's to help you make your goal more clearer, and second of all, to help out on making your shapes and proportions less stiffer, and more solid, fluidest, and lively.
Good luck with your new goal, and cheers to you.
