Gxsaurav you seem to be progressing fine. Keep it up.
At one time I also wanted to learn from the instutions like Arena and all, but gave up as at that time I couldnt justify the money as it did not fit into my bill.
At that time my brother gave me a free working version of blender
www.blender.org and since it was also available for Linux I started to experiment with it myself and learned a few things along the way.
Since its release as an OSS product a year or so back, Blender have been growing in features at incredile pace, it have now become a very strong tool for learning and doing 3d modeling and animation especially for the begginers as it is ver powerful allow very good animation capabiites, have hos of other industry standard features and costs nothing.
There is a very strong, vibrant and growing community of blender at
www.elysiun.com If some of you guys want to learn blender you can become members there and start learning. I go by the name of varuag over there. Alternatively you can post your queries to me also.
For the beginners and intermediate level users you can find some tutorials and other materials for download at my site.
