Flipped through your sketchbook and there is a great sence of improvement along the way. Lovely studies but I like your really loose sketches the best.
Some of them feel rigid or rushed at times, but when I see really fresh stuff like this and this I think you have great talent. Your comics could benefit greatly form this kind of fresh and loose linework.
Be loose and be bold with your sketches, and experiment with color too.
Keep em coming!
Many thx for your comment im my SB. Feel free to honestly crit me, I'm here to improve.
