1) This pack has been posted before. Yes, this exact pack has been posted before. The solid colors with the grid outline has been done to death. This pack is generally considered spam simply because everyone and their respective brothers have made it and posted it. You're not likely to get any praise from this because we're all sick of seeing this pack.
2) Please post screenshots without shaders. Shaders give a false impression of quality, something that this pack is lacking in. It looks good... until you realize it's that way entirely because of shaders and not because of the grid pack that you've actually published.
3) This is NOT the place to advertise your Youtube channel. We have an entire forum devoted to promoting Youtube channels. More to the point, if this pack is indicative of what's on your channel I can expect to see a lot of unoriginal stuff that I've seen done better elsewhere. That's what your pack is, and since you're using it as an advertisement I'm going to assume that's what your channel is as well. You're not going to get any views or subs giving us something that we're already sick to death of.
I know you probably think you made something special here, but just do a quick search for "Simple Craft" or "Flat Craft" and you'll almost certainly find at least a few other renditions of this pack. My sincere advice to you is to report your own post and politely ask a moderator to delete it. Come back when you've made something unique and interesting... and are not just putting a pack out there to promote your channel.
