Obviously, the results in the cup are what matters most. Without having something to compare to, or much to go on, a graph won't give too much objective information that you can use for feedback, but I'd be willing to bet you could get better results in a shorter total roast time. That much time after 1st crack probably flattened a lot of flavors and sweetness. I'll be curious to hear your impressions though.
You might want to consider mapping your ROR.

Hope you are roasting for espresso.
Great advice about looking at HukyForum. When you get over there lots of newbies and first roast advice. You really need to get into Artisan again and refine your settings. Your graph is really hard to interpret as is.
There is a great ABC in setting up Artisan that this lowly novice was able to follow.

Also consider checking that Linear Projection box. It will give you an idea of where your roast is headed and time to make corrections in advance.
And changing the Delta Axis to 100 so that your ROR graph stays below your roasting graph.

thanks for the tips. I rushed into that first roast because I was eager to try my new roaster, ive been doing a lot of reading and made some changes to artisan, I will post my second graph hopefully tomorrow

In my experience with the Huky 455 g is larger than the ideal batch size. The roaster gives better results and is more controllable with a somewhat smaller batch. I like 350 g in which gives about 300 or so out.
Overall your profile looks pretty darn good for a first roast. However, the charge temp looks a little high, especially for a lower grown Brazillian. Total roast duration is also pretty long, try to keep it around 13 minutes or less. Would also be helpful if you plotted delta BT and applied smoothing to your curves.

Also try extending your sampling interval, maybe to 3 or 5 seconds. Otherwise you'll have that spikey graphs all over. I had the same problem. Even with 5 seconds, you have plenty of time to correct in case your roast calls it for.
As said earlier, try lower charges. 300g or 350g. These loads are very controllable. Yesterday I tried 1lb (455g) charge, and although the curve looked nice, the First Crack "dip" was rather hard to control, same as the consequent flick upwards after the first crack (when the beans become endothermic). I also noticed some roasting defects that I did not see in my previous roasts. I some tipping and cratering (very few though).

So basically follow Scott Rao advice on this one as well - Don't use the roaster's full capacity. The sweet spot around 70% of full load
