Your chart looks correct but I am not sure how relevant the trend lines are when using HeikenAshe candles. These candles do not wholly reflect the trading for that day because they look at the average price from previous candles. If you want to trade trend lines and buy sell zones / horizontal support and resistance then I personally find sticking with normal candles is better.
I think it looks good. I can see support and resistance levels clearly marked, Both trend lines create a wedge pattern and you are looking for a drop to the downside with a profit target at the next support level. Makes perfect sense to me. It shows a clear trading plan and why you want to take the trade. Good work :)
