One of the artists I've been chasing for a long time is Ingrid Hardy. She does some amazing landscapes for various Star Wars sets, as well as spacecraft and characters that are also top-notch. I think she's done a little bit of superhero work in the licensed sketch card world, as well. Her Topps Star Wars sketch cards rightfully sell for quite a bit, as they are usually pretty awesome.
I follow Hardy on Facebook, and every so often she'll post an eBay listing or something she's listed on her Etsy shop. Often they sell before I even see the post, but a while back she posted about this Leia personal sketch card that she'd made available, and I was the first person to click through and get it. I was really excited to get an Ingrid Hardy sketch card, and also excited that it featured Leia, the subject of my biggest sketch card collection. I was surprised at how thick the paint application on the card is. Hardy art has a lot of texture to it, and it is surprisingly detailed for how thick the paint looks.
She also included this autographed base card from Star Wars Galaxy that features her work on the front. This gives you a good feel for her Star Wars landscapes. I especially like some of the ones she's done that show action on the ice planet Hoth, with AT-ATs looming on the horizon. I also like the way she paints clouds.
She included a couple of business cards with some more art and her contact information and her website link on them.
I was pretty happy to get an example of Hardy's artwork for my collection, and especially happy that it featured Leia from Star Wars.
