Layers Pro App Vs. Oil Pastels

After experimenting with different layering and blending techniques on the 3-D shapes on both the iPad and with oil pastels I have learned alot about different techniques.  Using oil pastels, it was harder to blend the colors as gradually as you could on the iPad.  On the app you could gradually lighten or darken shades which was alot easier to control than trying to blend black or white in with an oil pastel.  The smudge tool on the app also was very convenient, it blended the colors into each other alot easier that oil pastels because there isnt really anything you can blend oil pastels together with well.  My only complaints would be that the shadows were hard to draw and it was more difficult to get precise lines with the right thinkness then it would be with regular oil pastels.  Technology is becoming more importiant in todays society and therefore it is importiant to incoporate it into art.  A big advantage of using technology for art is that it is easier to share.  It is also much easier and cheaper to create artwork electronically because you dont need to buy all the expensive supplies.  While this is an improvement in the art world, it in some ways defeats the purpose and talent needed to be a good artist.
