Goblet:

Update:

Goblet without Transparency:

Made in Blender 2.45

Comments are appreciated.

The shadow seems really odd, and the colors are not the good but otherwise great

Its the angle of the camera, I need to get used to the blender cam.
Otherwise thanks for your comment.

Nice 3D work. I (tried to) created a character in Maya myself last week, which turned out pretty well for a first character actually. I have some trouble making an animation file though, perhaps anyone can help me. I render, and Maya makes 100 (depends on the amount of frames) files. Sometimes .tiff, or whatever I select. But how to go from here? I've got Adobe After Effects, but I don't know much about that program. Can I use that program to make an animation, and if so, how?

Go to Maya's Render options and change the format to AVI perhaps?
I never used Maya to be honest, so I'm guessing
Other than that thanks for your comment.
ALSO i shall upload my human head soon, it's my first head and my 3ds max teacher said they are pretty difficult to make.

Yes would be great. I'm eager to see!  

Nice goblet !
may be you try increasing ray transp.  depth to make glass  less dark.

Usually, you save the frames in tiff/hdr formats. (high dynamic range image is advisable
as you can change lighting conditions after render.) then open the first frame with
photoshop cs3 and check "image sequence" option. select required frame rate and
you will have a video layer in CS3. apply different adjustment layers, convert it into
a smart object and you can apply as many filters as you like. while preview it in
animation window.

CS3 can render it directly as a video ( cinepack or quicktime) but  again, you
can have CS3 to save individual frames as jpeg in another folder.

last you'll need is a tool like virtual Dub.
Import jpeg frames and select effects like motion blur/ audio sync / clip edit etc.
finally select a high quality and compression codec like Divx or Xvid.
and save your video in smallest filesize and best quality.

Hope this helps.
