http://www.shutterstock.com/sets/927619-pa....html?rid=10757You see ah, a lot of people PP for digital viewing only. Ask them about PRINT and they go blank.
For MPA level qualification and competition, we're judged based on PRINT. This means people like Keda, will have to edit as such and the PP itself would have to also look great (or even better) in print.
You have a 600D.

good. Your 60D works like my 60D.
Let me show you this

That's my photo. I've been featured there for some 2 years now.

EOS 550D. 50mm f1.4. 580EX II flash. Shot was done in about 2 minutes, it was just a food that's on display at an event. Manipulation of single flash with environment.
In short - the moment you start to think your gear is limiting you, that's it. You're not going to be progressing already.

Eh no no , i meant the price of his printing product

and , waa so lucky to have top used service provider.
his wedding package I donno la, last I heard is 5 figures type.

budget RM 20k first la.
now back to the topic.
RM 30,000 type printer used to print the works that are sent to competition.

Like I said - judged on print. Judging done by top-caliber photographers.
Why judge on print? By having good print, it shows the photographer is competent in the post process, not just the digital part of the workflow but also down to choice of printer, print material, and so on so forth.
For me, I've not bought any lens for a few years now. I spend on International level competitions. Money goes to the participation fees, print cost and print shipping.
If you get good grades, those become bragging rights.

Whether you get good or bad grades, you get to know where you stand - INTERNATIONALLY.
And not only that, these competition also give you feedback. From your score, you get to know how good is your image. For example last year's competition, I was quite confident that my photos were good enough but to face with the harsh reality that all my photos were good BUT fall short of the grade to be given recognition.

Many of my photos are 2 points short of their 80 points requirement to be given a merit prize.
Put it simple, I pay to get to know where I stand, and to get feedback from experts.
All in all it's about where you want to head to in the photography world. You want to advance in your gear or advance in your art?
Will you be a painter with 3 brushes that produces beautiful art? Or a painter with a whole lot of high-grade brushes but produces mediocre work?
