Hi Ashok,
First off, great work. Your writing is coming along superbly. Just a couple of pointers over and above why everyone has already said here.
For paper:I use the Bilt Executive Bond 85gsm printer paper. You can also get 100 gsm paper which also works really well too.
As you are in Mumbai, keep the paper ream in an airtight plastic paper wrap until you are going to use it. If you leave it out for a while, it can start feathering when you specially use fountain pen ink. This happens to me,in Pune itself, which is quite a dry place.
What ink are you using?
Have you ordered Walnut ink crystals from PIA? If not, Send me your address by Personal message and I'll send you some. It writes beautifully.
For guidelines:Check out this thread and Reply #4.
http://theflourishforum.com/forum/index.php?topic=3322.msg45957#msg45957I have explained how to use and makes guidelines.
You can print this out on the sheet and write over the guidelines. Initially it helps me such a lot.
Salman had advised me about this earlier too. height to width ratio is critical in Copperplate. Try to keep it to width = half height. It's all mentioned in the above thread.
Another very important this I was told by all in this Forum during my early practise:
Don't bother about flourishing. Once you have the letter form down, it will come naturally. You have superb pen control from what I have seen in your other work on IG.
In this style start focus on ovals. They are the CORE of this style of writing.
I use practise words like, minimum, cooeeing, hillbilly, saudade, schwarzkopf vexed iraq big time in july.
You've said that your order has already gone out to PIA. But trust me, you will be ordering a lot more very soon. This is a very addictive art form. For future reference read through this thread for tools and supplies

Happy writing
