I agree with what Jakerpot has been saying - the praise is well deserved!
The shading on the far right machines is brilliant - just the perfect amount of dithering to make it look like real game graphics.
Please don't change the palette unless all other options fail and the fate of the world hangs in the balance - this is one of the most effective colour schemes I've ever seen.
I fell in love with this project instantly - I don't know how serious you are about it, but for me, I'd put this in a list of Top Ten Most Promising Mockups. The creativity here (ninja in a cool land of techno-food) is off the charts and you may count me as a fan. An uber fan.
If the project I'm working for (
The Amazing Wilbot Project) winds up looking even half this cool and fun I would be happier than a happy clam in happy sauce.
Your ninja reads fine to me - the minimal style actually concentrates the coolness, and it is shocking to me how much character shines through with such a small number of pixels. Please don't change him into something like a "chef"! No offense to chefs, but while they may be something to respect, they are
not associated with coolness, and the
power of this mockup (for me) comes from the delightful juxtaposition of cool and whimsical. Without the ninja, there isn't enough 'cool' and thus no juxtaposition to so strongly catch the eye!
I would have posted earlier, but all I had was love and nothing useful - but I am spurred into action now to 'help' the project by giving you as much assurance as I can that you are doing
great (better than great, even) and that depression is the farthest thing you should be feeling right now. Triumph is what you are brewing - I can recognise the aroma from here!
(p.s. if anybody complains too much about your dithering, please ignore them - you've been using it with impressive mastery from the start. In fact, when you changed your columns, you kinda reduced them to looking like ice or crystal tiles, which is a shame, because the stone you had was simply
amazing. Hope I haven't scared you with a wall of text, I just couldn't help but express myself about your project! Don't mistrust your incredible pixel instincts, they're spot on so far!
