Text is always hard for me and I honestly never add text so I don't like any text in the sigs I make.
The right side of the render looks sorta cut off strait down and some parts look low quality on the render like you smudged over it, but over all it's a great first(if it's your first) sig. I think if the render was all the way to the right with the side I said that looks cut off right on the end, the sig would look better imo
on the 2nd imag the render looks a bit better but the shield looks lq
keep it up I wana see more.
