Finally, I can show off this piece of work that I made by hand and is decent enough to be displayed in the hall for the whole summer.
I mainly used the rounded rectangle tool in CorelDraw software to draw a rounded rectangle, then used the "Picture Frame Precision Crop" option under "Effects" to place the picture into the rounded rectangle. (This tool is very powerful and quite important.) Then, I appropriately added color transparency using the Transparency Tool. Lastly, it's the text. Just pick some favorite fonts and you're good to go. Slightly outline the edges to make it blend with the scenery, and that's it!
Hehe, I personally think it looks pretty good. Hehe, I wonder if anyone noticed that the scenery inside is actually a corner of Orange Isle. Hehe, according to personal preferences, different landscape images and main colors can be chosen to create different effects.
Here's my 'Green Oasis of Oranges' for everyone to take a look! Haha, it can definitely be collected as image material.
