I’d make that first image equate to how you want to be perceived. Right now that sketch of whatever it is is not working for you. It made me not want to click further. Make sure that first image engages people, encourages them to explore more, and most importantly, clearly communicates the type of designer you are. Be specific and clear. People don’t have a lot of time so don’t assume they will spend more than 5 seconds before deciding to click deeper or close the browser window.
