When I brought my first copy of Photoshop a long time ago I could not wait to get on it, then I saw all was not so simple (well that is the same with all things you do not know how to do).
This is why Photoshop tutorials are so good to help anyone how wants to learn something new about Photoshop (in life we all can learn new things).
Check out this tutorial on how to make 3D Tentacles in Photoshop.
If you got any tips or Photoshop tutorials you would like to share you can do so in the comments field.
