Nice drawing, my eyes are bleeding from the color choice on text though, so didn't read much of the post.
Yea, there are several flaws with this drawing. Using the pencil I did is like Chinese calligraphy, you cannot go back and redo, it must be left alone. Lol Edit: I may just redraw it. Dunno yet
I see it's a good drawing but personally, I don't believe it's as good what people say to be honest... The scaling is all wrong, there's several ways to improve this though, most common way of getting perfect scale is grid drawing. Basically spilt the picture in to a grid, 3 x 3 is normal but more complex the more you split the drawing up. And you draw the picture out as individual sections, if you needs help on this there's many videos explaining how to do this. If you did that it would improve the drawings greatly improve but for a gods honest option I say it's more 4-5/10 scale is one of the most important things about drawing.
Thank you Yea, I drew this out of boredom, and I admit not much scaling went into this. There are many flaws with this drawing, as stated before; however, thank you so much for the suggestion to improve and your honest rating. If you want to see some of the best of my work, you can find it in Fan Creations under the "S4 Air vs. Water banner" or something like that.
