Thank you for your positive feedback, I appreciate it.

I am still working on getting an english version of my website online, it is not as trivial as initially thought since the software in use doesn't natively support multi-language sites.
I am still in a very early stage, as of now I have just created three drawings on request, all others have been done for friends and family. I hope to have soon enough drawing to organize a little exposition from it as originals still always look better than any digital photo.
Personally I believe the price for a digital-only version are justified. After all the work and material needed is the same for a digital version, only shipping is not needed then and reduces the cost.
Normally I deliver without picture frame, since everybody has another idea about how it should look and it also depends on where you place the picture in your house. Though a simple, regular picture frame would cost ~$20 if you require the picture to be framed.
